Thermoplastic Films

Filler-related advantages:

Neuburg Siliceous Earth and Calcined Neuburg Siliceous Earth

  • low moisture content, low moisture absorption
  • high fineness
  • excellent dispersion properties
  • very low sieve residue
  • high brightness and color neutrality
  • high hardness
  • temperature resistance
  • polymer-specific adaptation via surface treatment

Effects in films:

  • low coefficient of friction, antiblocking
  • good transparency/high light transmission in the visible range
  • high gloss or matting
  • low haze or higher haze
  • hardly any adsorption of additives thanks to relatively small surface area
  • improvement of film processing/manufacturing properties by increasing modulus
  • IR barrier
